In need of ideas again. Since getting the truck on the road again, I can't seem to get it to run where I had it before. This is on a '60 235, 2 Stromberg 97's, Fenton headers. I used to run it at the BB. Pre68Dave's site shows it to be 5 deg. advanced. Now I have trouble at zero degrees represented by the vertical line between the U and C. The only changes I can think of is that I changed one of the carb's base plate to have ported vacuum. But I have the issue whether I use the vacuum advance or plug the line. I did not use the vacuum advance before. The other change is I had the head off chasing a knocking problem that turned out the be a deformed oil pan. One more change was to the exhaust where I routed both pipes to the drivers side instead of one on each side. Almost forgot, I did pull the distributer for painting but did make any changes. New wires, plugs, points, condenser. Any ideas?
